Definitions
- the invention relates to a device for filling containers with a liquid product, in particular to a device for filling glass bottles with beverages.
- the invention thus relates to container treatment machines in the beverage industry, in particular container treatment machines with outputs of more than 1000 containers per hour, in particular container treatment machines with an output of more than 10,000 containers per hour.
- the invention relates to container treatment machines which are designed and set up as so-called filling machines or fillers for filling the containers with liquid contents, in particular with beverages.
- Such filling machines of the type mentioned, namely devices for filling, have a large number of treatment stations or positions which can also be understood as filling stations or filling points or filling positions.
- a filling element or filling element with a filling valve or liquid valve is provided, via the discharge opening of which the liquid filling material is discharged into the container.
- a container carrier for example with a container plate, is generally provided at each filling position, via which the container to be filled is lifted towards the filling element by means of a vertically oriented lifting movement and is brought up to it and pressed against it.
- the containers can also be gripped in the neck area and thus pressed against the filling element.
- the filling material is dispensed into the container under pressure by means of what is known as “pressure filling”, in which the container to be filled is subjected to a pretensioning pressure before the filling material is dispensed.
- a glass container can burst during pre-tensioning with tension gas or during filling with filling material until the pressure is released.
- glass splinters which represent a high risk especially in the food sector when filling beverages and are to be regarded as a particular hazard. It is well known that cullet and splinters that get into containers have numerous negative consequences. Quite apart from the health risk for consumers, broken pieces in the container can lead to product recalls, loss of prestige and the manufacturer's loss of market share.
- DE 10 2014 103 504 A1 describes a device for filling containers which is designed as a filler carousel and in which a surge device is provided to remove glass breakage residues, in particular shards of bottle bottoms, from the container plates of the container carriers at a filling point.
- the surge device comprising a surge pipe and a surge nozzle can be designed to rotate with the filler carousel.
- the surge nozzles are arranged in relation to the axis of rotation of the filler carousel radially outside the container carrier of the filling points and at a level below the container plate and are aligned so that a surge media jet emerging from a surge nozzle is directed inwards towards the axis of rotation and aims through below the container plate.
- the surge media jet is deflected via a deflection device additionally provided on the container carrier, so that the surge media jet sweeps over the surface of the container plate and container fragments are washed away to the outside.
- EP 0 615 947 A1 discloses a revolving filling machine with a ring bowl attached to the rotor, in which a ring-like free space is formed between the ring bowl and the rotor, which is open at the bottom and the top and is delimited on the inside by a cylindrical protective wall.
- a pipeline is provided above the free space with several spray nozzles that coat the ring bowl, the ring-like free space and the delimiting protective wall.
- a spray jet emanating from the spray nozzles is oriented vertically downwards and coming from the outside inwards, towards the axis of rotation, whereby impurities carried along with the spray medium, such as glass splinters, can flow away unhindered via the free space.
- a pressurized liquid can be applied to the pipeline manually or automatically in order to carry out a spraying process for one or more rotations of the rotor.
- DE 27 39 742 A1 also discloses a filling machine with several filling positions distributed over the circumference of a rotor, each with a filling element and a container carrier, in which a vertical spray tube is provided at each filling position, which is located between the container carrier and an upper flange is attached to the associated flub cylinder.
- a plurality of essentially horizontally directed spray nozzles are formed in the spray tube, the spray jet of which is directed outwards away from the axis of rotation.
- the spray tube is also connected to a spray nozzle provided in the container support, which can discharge a vertically directed spray jet from bottom to top. The supply of the spray medium to the spray tube is released by a separate, mechanically operated valve.
- This valve is actuated by the lifting cylinder, and only when the lifting cylinder executes a lifting movement that is greater than the normal lifting movement required to press a container against the filling valve.
- the lifting movement of the lifting cylinder is limited by this container. If, for example, the pressed container bursts, the lifting cylinder sets the Stroke movement continues, and thus actuates the separate valve.
- the disadvantage here is that an injection molding process can only be carried out at the filling position that is directly affected, specifically only when a broken glass event occurs. Adjacent filling positions that have been affected cannot be cleaned, so that there is still the risk of cullet or splinters entering the container due to splinters adhering to such neighboring filling positions.
- the object of the present invention is therefore to provide a device for filling containers with a liquid product which avoids the disadvantages of the solutions known from the prior art and which in particular allows an effective, individual and needs-based removal of impurities and glass breakage residues and thus enables a safer mode of operation.
- the present invention provides a device for filling containers with a liquid filling material.
- the device has a rotor that can be driven revolving around a vertical machine axis and has multiple filling elements distributed over the circumference of the rotor, which are connected to a provided filling material container for the liquid filling material, with multiple spray nozzle units being provided that can be acted upon with a spray medium and rotate with the rotor are.
- at least one circumferentially moving spray nozzle unit is permanently assigned to each filling element and a nozzle opening of the spray nozzle units faces the respectively assigned filling element.
- the Spray nozzle units are individually controllable, for this purpose the spray nozzle units are equipped with suitable, controllable valves and a control unit which communicates with the spray nozzle units is also provided.
- a device for filling containers with a liquid filling material is to be understood in the understanding of the invention as a rotating filling machine or as a rotary filling machine and is also referred to here as a filling machine, filler or filler carousel.
- a filling machine comprises several filling elements which, together with several container carriers that also rotate with the rotor, form a large number of filling points or filling positions. Between the individual filling positions or between the individual filling elements, for example, flat dividing plates can be attached, which are oriented radially in such a way that two dividing plates form a lateral boundary for a type of chamber at each filling position for each filling element, each separating plate with its two opposite one another Flat sides facing adjacent filling elements.
- each filling element can be sprayed independently of a rotational position of the rotor, since at least one spray nozzle unit, which moves along with it, is specifically assigned to each filling element.
- the fact that a nozzle opening of the spray nozzle units faces the respectively assigned filling element can also be understood to mean that the nozzle opening is designed and oriented in such a way that a spray jet or spray medium jet emerging from this nozzle opening of the spray nozzle units onto at least a section or sub-area of the associated filling element hits, whereby at least this section or sub-area is hosed down and cleaned.
- a spray nozzle carrying the nozzle opening or a spray nozzle body carrying the nozzle opening can be arranged or fastened on the rotor or also on the respective filling elements themselves.
- individually controllable spray nozzle units are to be understood as meaning that the spray nozzle units can be or are controlled individually, specifically in such a way that the Spray nozzle units can be switched in a controlled manner by opening the corresponding controllable valves and also closing them again by means of the controller. In the present case, this is also understood as activating the spray nozzle units. Spraying processes can therefore be triggered and carried out in a controlled manner.
- the spray nozzle units can be switched as required, i.e. they can be activated individually, in groups or in groups.
- a spray-discharge process can be triggered or initiated and carried out individually for each filling position due to the individually and arbitrarily possible controllability and switchability of the spray nozzle units. It is particularly advantageous that the spray nozzle units can be controlled and switched on individually and in groups due to this controllability and switchability. For example, when a glass break event occurs at a certain affected, critical filling position, not only this filling position can be specifically sprayed or cleaned, but also, as a precaution, the filling elements of the two immediately adjacent filling positions and, if necessary, further neighboring filling positions, namely filling elements in front of and / or subsequent filling positions, be hosed down or cleaned.
- the switching or switching on of the spray nozzle units takes place preferably regardless of whether a container is present at the filling position, in particular in a sealing position with the filling element, or whether the filling position is without a container, namely empty.
- This extremely advantageous design makes it possible, through the use of a suitable controller, to trigger one or more spray-discharge processes at any desired point in time for each filling position or for each filling element or also for a group of filling positions or filling elements.
- the solution according to the invention not only offers the possibility of shards and splinters to remove corresponding filling positions, but sticky product residues from filling tubes, probes, and return gas tubes as well as other components in the vicinity of the filling elements can also be removed. Since it is also known that cullet fragments stick to the sticky product residues mentioned, such sticking can also advantageously be avoided.
- the spray nozzle units are arranged radially on the inside with respect to the machine axis relative to the respectively assigned filling elements, the nozzle opening of each spray nozzle unit facing an inner side of the assigned filling element pointing in the direction of the vertical machine axis and an inner side of the assigned filling element extending from the spray nozzle unit Spray jet is directed away from the vertical machine axis and towards the inner side of the associated filling element.
- those areas with spray medium can also be achieved which are located on the inner side of the filling elements, for example in the often stationary and non-circumferential external spray devices known from the prior art and thus cannot be reached by the spray medium and thus according to Form spray or spray shadows according to the state of the art. Even if such spray jets or spray jets coming “from the outside” are of considerable strength, they do not hit the inner sides of the filling elements lying in the spray or spray shadow. In the preferred embodiment of the device according to the invention, cleaning of the filling elements can therefore also and in particular be ensured on the inside of the filling elements.
- Adhering splinters and / or product residues which occur on the inner sides of the filling elements in the spray or spray shadow of conventional spray nozzle devices, can thus be removed successfully and effectively. This also makes an advantageous contribution to product safety. This prevents splinters or cullet residues from sticking to components of the filling element, which for example also counteracts undesired entry of cullet or cullet residues into one of the following bottles.
- the spraying described here is particularly beneficial when filling fruit juices, as sticky residues can form on the filling pipe or on the filling level probe or on the return gas pipe etc. when filling such products, to which even the smallest fragments of cullet can stick or stick. which come into direct contact with the product during one of the next filling processes and consequently loosen during the filling process and fall into the bottle.

- a control unit 14 (not designated in FIG. 1, see FIG. 3) communicating with the spray nozzle units 6, 6 'is provided and the spray nozzle units 6, 6' are equipped with suitable, controllable valves 13 which are protected together in the Interior 9 are arranged.
- the controllable valves 13 can be in the form of pneumatic controlled media valves. However, electrically controlled valves are also possible.
- Each spray nozzle unit 6, 6 ' is preferably individually controllable, whereby several spray nozzle units 6, 6' can of course be switched at the same time, so that a spraying process can be triggered with several spray nozzle units 6, 6 ', which are combined in any groups provided as required . In the present case, this is synonymous with the fact that the spray nozzle units 6, 6 'can be switched individually and as required, as well as in groups.
- both the filling element 3 can be hosed down and cleaned at this affected filling position "eleven", but at the same time the filling positions FP " ten “and” twelve "as well as the filling positions FP" nine “and” thirteen ", etc. can be hosed down or cleaned.
- the spray nozzle units 6, 6 'can preferably also be switched at intervals. If, as in the example shown in FIG. 1, several spray nozzle units 6, 6 ′ arranged vertically one above the other are assigned to a specific filling element 3, the topmost
- Spray nozzle unit 6 are controlled in order to trigger a sequence of spray jets there with a predetermined time interval.
- the spray nozzle units 6 arranged below can, for example, also be activated at intervals but with a time delay to the top spray nozzle unit 6 so that the filling element 3 is thereby successively sprayed from top to bottom, preferably with several spray pulses.
- FIGs 2 and 3 illustrate once again the arrangement of the filling elements 3, the protective wall 8 and the spray nozzle units 6, 6 'on the rotor 2, specifically relative to one another and relative to the machine axis MA.
- the filling elements 3 are arranged radially outside in the outer space 1 1, the spray nozzle units 6 (omitted in FIG are arranged.
- the nozzle openings 6 a of the spray nozzle units 6 face the inner side IS of the filling elements 3.
- FIG. 4 shows a schematic circuit diagram for a control in a preferred exemplary embodiment of the present filling machine 1, wherein in the exemplary embodiment each filling element 3 is additionally equipped with a pressure sensor 16 for measuring the pressure prevailing in the container.
- the pressure sensor 16 is in communicating connection with the control unit 14 for controlling the valves 13 of the spray nozzle units 6, 6 'and permanently measures the pressure prevailing in the container to be filled.
- the control unit 14 for controlling the valves 13 is designed as an integral part of a central electronic control device 15, to which the corresponding measurement data from the pressure sensors 16 are transmitted and which the filling elements 3 or the dispensing of the liquid filling material by means of the filling elements 3 in controls the container.
- each pressure sensor 16 communicates with the control unit 14 for controlling the valves 13, which outputs control signals for switching the controllable valves 13 of the spray nozzle units 6, 6 ', using the measurement data from the pressure sensors 16 or from in an evaluation unit of the central electronic control device 15 processed evaluation data of these measurement data.
- a pressure sensor 16 measures a sudden drop in pressure at an affected filling position FP, which occurs, for example, due to a broken glass
- these measurement data are used to immediately via the control unit 14 at least the controllable valve 13 of the injection nozzle units 6, 6 assigned to the filling element 3 of the affected filling position FP 'to switch controlled, namely to open in order to spray off the affected filling element 3 or to wash off.
- at least the controllable valves 13 of the spray nozzle units 6, 6 ′ of the filling elements 3 arranged adjacent to the filling element 3 concerned can preferably also be opened in a controlled manner via the control unit 14.
